IMPROVEMENT IN REGULATOR FOR DRAWING-FRAMES.

The Schedule referred to in these Letters Patent and making part of thesame.

Evener for Machinery for Drawing a Cotton or other Fibrous Sliver; and 1do hereby declare the same to be fully described in the followingspecification, and represented in the accompanying drawings, of Which--Figure 1 is a front elevation,

Figure 2, a rear elevation,

Figure 3, an end elevation,

Figure 4, a vertical and transverse section, and

Figure 5, a horizontal section ofthe machine.

On January 28, A. D. 1851, a patent for a drawing regulator was grantedto Newell Wyllys, such patent having been reissued, July 12, 1864, andextended for seven years, on January 20, 1865.

The machine of the said Wvyllys, although calculated to produce evennessof the sliver', is liable to effect too great a draught of it undercertain cir'cumstances; that is, when the sliver may have been drawn toits proper size, it is liable, at times, to be run with so much velocitythrough the trumpet as to increase the friction therein to such anextent as to cause the trumpet to be drawn forward, in which case, anincreased and unnecessary draught of the sliver necessar'ily follows.The reverse of this happens when the vsliver' moves with less thanaverage speed.

To prevent this result of the increase or diminution of friction of thesliver' in the trumpet, is the object of my additional mechanism; andthis mechanism is to produce a greater leverage or action of the weighton the trumpet, in order to hold it back, or prevent it from beingpulled forward by increase of friction of the sliver' in the trumpet,when such sliver may be ofthe proper size, and a less leverage or actionof the weight under the opposite circumstances. A thoroughly even sliveris what is desirable, and to eiect suc-h is the purpose of my additionto the machine, or drawing-regulator', or evener of Wyllys. Therefore,

The nature of my invention consists in the combination of the saidmachine of Wyllys and a mechanism substantially as hereinafterdescribed, or its equivaient, whereby the weight or leverage on thetrumpet shall he eitherincreased or diminished as maybe necessary, asthe velocity ofthe sliver' may be either increased or diminished undercircumstances and fi'orn the cause above stated.

vWhile running through the trumpet, should the sliver be too large, itwill draw the trumpet forward, and if too small, the trumpet will fallback, land as a consequence, thr speed of the drawing-rollers will bechanged; but in order to insure thorough evenness of the sliver, theadditional mechanism, to be hereinafter explained, becomes necessary.

In the machine of Wyllys, or that as represented in the drawings, whenthe sliver in the trumpet ,is of the right size, and the speed and otherconditions are favorable, the friction of the sliver in the trumpet willbe balanced by thc small weight c, suspended from an arm, b, projectedfrom the trumpet-shaft c, the trumpet being shown at tl. l

Should the sliver be too large, and the trumpet, in consequence thereof,be. drawn forward, the arm will raise the weight. So, should the sliverbe of less size than it ought to be in the trumpet, the weight willdepress the arm on which it hangs, and thereby cause the trumpet to fallback.

The first three sets of drawing-rollers, e c e, will be driven at oneuniform speed, by means of a belt, going around a pulley, f, fixed onthe driving-shaft g, and also about a pulley, h, on a shaft, t, on whichis a pinion, 7c.

This pinion engages with a gear, Z, fixed on the shaft ofthe lowerroller of the first set of drawingrollers.

On the driving-shaft gis a cone-drum, or pulley, m, and above this,another' cone-pulley, n, which. is larranged with its lesser end over'the greater end of the cone-drum or pulley m.

The upper cone-drum is connected with the back roller o of the front setof drawing-rollers, and also with the lower of the calender-rollers p q,by a train of gears o', z, t, u, c, and w, the same being as representedin the drawings.

An endless belt goes about the two cone-pulleys, or' dr'ums, and througha movable guide, x, applied to a.

tr'aversingscrew, y, which, in connection with other mechanism, operatesto eiect the lateral movements of the beltguide.

On one end of the screw is a gear, z, above which are suspended twopawls, a b', which stand iu opposite directions. On the screw-shaft, andby the side .of the gear z, and also under the pawls, is a disk, or

escapement-wheel, c', which, when turned into a certain position, willkeep the pawls out of action on the gear, but when turned out of suchposition, in either' direction, will allow one of them to descend intoen gagement with the gear.

The pivot-pins of the pawls are supported by or projected from avibrator, or lever, d', whose fulcrum is the screw-shaft. A continualoscillatory motion is imparted to the lever d', by a crank-wheel, e',and a.

tory movements ofthe trumpet may produce corresponding rotary movementsof the disk c.A

When the friction of the sliver in and against the from thetrumpet-shaft,) by means of a rod,`7t, which is jointed to such arm,such being s o that the vibratrumpet is balanced by the weight a, thedisk will be in such a position that neither of the pawls will be inengagement with their gear.

Should the trumpet be moved forward, by reason of an enlargement of thesliver, the disk Will be turned so as to let one of the pawls down intoaction upon the gear, thereby 'causing the screw to be revolved in amanner to move the belt-guide laterally, and to effect the consequent orsimilar movement of the belt thereof along its cone-drums. The result ofthis will be a change in the relative speeds of the draught-rollers. Theback ones will not vary their speed, but that of the ont ones will beeither increased or diminished.

When the sliver may have been drawnto its proper size, the trumpet willbe restored to its normal position.

The above, with the framework, as represented, constitutes most of thesubstantial characteristics, and mode of operation of the Wyllysmachine, or drawing regulator, orevener, as it is termed.

My addition thereto may be thus explained:

Within the frame m', by which the belt-shifting screw is supported,there is arranged aA shaft, n', which is parallel with the screw.

'From the said shaft, two arms, o p', are projected, as represented. Oneof them, viz, that marked p', extend up towards the Weight a, andreceives a pin, q, which projects from the Weight.

The other arm turns on its shaft, and alongside of a sector, o,projecting therefrom.

A clamp-screw, w', going through a curved slot, s', made in the sector,and screwed into the arm o', serves to clamp such arm to the sector.

A rod, t', has one end supported in the arm o', and the other in the arm1)'.

The rod t', arranged over the shaft n', is made to stand more orless'obliquely with respect to such shaft, bysimply moving the arm o',on the shaft, as a centre, and subsequently setting up the clamp-screw.

The rod t goes through a notched projection, u', or the equivalentthereof, extended from the belt-guide x.

From the above, it will be observed that While the said guide x is beingmoved laterally, it will cause the rod t to move more or 4less eitherforward or backward, so as to move the longer arm, p', and thereby causethe weight, a, to be moved along its supporting-arm that is, .eithernearer to or further from the trumpet-shaft.

It will readilybe seen that by this means lthe Weight or leverage on thetrumpet may be automatically changed,:as may be desirable, to counteractthe tendency of the increase or decrease of friction of the sliver duetothe increase or diminution of velocity of the sliver, When it may beof the right size to impel the trumpet forward or allow it to fall back.

What, therefore, I claim as my invention,is-.

The combination of the additional mechanism, viz, the notched projectionu, the oblique rod t', and the arm p', or the mechanical equivalentsthereof, with a drawing-regulator, or evener, of the kind substantiallyas described, .the purpose of such additional mechan ismy being as setforth.

Also, the combination` of the slotted sector, lr', the movable arm o',and the clamp-screw au', or their mechanical.equivalent,with the notchedprojection a', the rod t', and the arm p', when .they are combined'witha drawing'regulator, and for operating its movable weight, substantiallyas and for the purpose specified.
